METAL WINDOW.

Application filed November 3, 1927. Serial No. 230,754.

This invention relates to hollow metal window frames of the construction shown and described in an application for Letters Patent of the United States of Alphonsus Fien, Serial No. 230,755, filed concurrently herewith, and is particularly concerned wlth the strengthening of the frame at each upper corner where the jamb and the head of the frame are secured together, the purpose belng to provide such constructionthat theframe shall be capable of resistmgbreakagepr distortion in the rough handling to which such frames are sometimes subjected in transportation and in erection on the ob; The invention is also concerned with the support of the sash pulleys, the houslng of the pulleys at each side being of such character as to permit the use of pulleys of substantial diameter, so as to carry the chains properly and to permit each chainto be carried in the recess of the pulley stile, at one side of the pulley, and to be carried centrally over the weight in the hollow jamb or weight box. 7

The. pulley housing is so constructed as to serve the purpose of strengthening the frame at the corners as above mentioned.

The features of construction in which the present invention is embodied are illustrated in thedrawings described in the specification of the application above mentioned Serial No. 230,7 55, but, being the subject of a separate and independent invention, are also shown and described herein, like reference characters being employed, as far as possible, to indicate like parts in the. two cases, for convenience in enabling the relation of the two inventions to be understood. In the accompanying drawings, in which the present invention is illustrated;

Figure 1 is a view in front elevation, as seen from the inside of the window, of the upper left-hand portion of a window frame which embodies theinvent-ion, portions of the jamb and of the frame head being shown as well as a portion of one of the window sashes, the jamb and the head being partly broken out and shown in vertical section;

Figure 2 is a view of the same as seen from above, the cap of the head being removed and a portion of the inturned flange of the head, at the outside of the window, being broken out.

The complete window frame includes a head, a sill and two jambs which are iden tical except for reversal. Each jamba may be made of a single sheet of metal, formed to suit the window opening in the wall and to receive within it the counter-balance weights, not shown, for the upper and lower sashes, the upper sash being shown in part in Figure 1. 1 i e r The edge portions .of the sheet of metal which forms the. jam are-bent toward each other and again toward the back of the jamb to form jamb members a and a the edges being again bent toward each other, in a plane transverse to the plane of the window, to form flanges as at a and a, which are spaced apart throughout the vertical helghtof the frame. The j amb thus formed is st fiened and strengthened and its edge portions maintained in. proper spaced relation by heavy metal reinforcing plates as more particularly described in said application Serial No. 230,755. The upper jamb reinforcing plate I), which is shaped to fit against the jam'b portions a and a on the inslde, to maintain the edge portions of the amb against relative displacement, is formed at its upper edge withtongues b 5 and 6' for connection with the head of the frameas hereinafter described, being thereby held from relative displacement in a vertical direction.

The pulley stile, the upper section 6 of which is :alone shown in the drawings, is formed to fit between the members a and a of the jamb and :is bent to form projecting vertical rails which, between themselves and with portions a andu of the jamb, form the grooves to receive the flanges of the upper sash z and the counterbalance chains, one

of which is shown at Z in Figure 1. Each pulley 0 is of such size and is so disposed and supported, as hereinafter described, that the portion of the chain Z which lies in the groove of the pulley stile, is tangent to the pulley in the plane thereof, while the other portion of the chain, which is connected at its end to the sash, is also tangent to the pulley and in the plane thereof.

The soffit m of the head m is grooved as at m to receive the flanges across the top of the upper sash i, and within the head, extending from the inner face to the outer face, is a heavy metal reinforcing plate at, which is formed with slots n, n andn and is formed at its inner edge with a downwardly bent flange, as at a to bear against the inner face of the head and at its outer edge with an upwardly turned flange, as at a to bear against the outer face of the jamb. The tongues 6 b and b of the upper reinforcing plate Z) pass up through a slot at m in the soflit m and past the end of the soflit through the slots n n", and a in the reinforcingplate a and are bent over upon the reinforcing plate a securing it rigidly to the frainehead. A tongue 0; of the jamb is also passed up through the slot on? and is bent over in a direction opposite to that of the tongue 1) The jamb is also formed with tongues a and a which are passed up through slots m and m in the inwardly turned edge of the soffit m and are bent over toward each other. At its outer face the jamb is formed with a tongue a which is bent over upon the edge of an extended tongue m of the sofiit. At its inner face the solfit is also formed with an extended tongue m, the upper edge of which is bent over upon itself as at m and is cut out to form two shoulders m and m The inner Wall of the jamb is bent over upon the extended tongue an" of the sofiit and has a tongue at which is bent down between the shoulders m and m. In this manner the jamb is rigidly secured to the frame head to prevent rela tive displacement in a verticaldirection and at the same time is secured rigidly to the frame head to prevent relative displacement in a horizontal direction.

Each pulley 0 is mounted to turn on a spindle 0 which is held in downwardly extended ears 0 of a guard housing 0. The latter is conveniently secured in placeon the reinforcing plate a by lugs 0' of the housing 0 which are passed down through slots, indicated at n in the reinforcing plate a. It will be understood that the guard housing and the pulleysare set somewhat obliquely with respect to the plane of the window so as to bring the parts of the chains properly in line with the sashes and the counter-balance weights.

corner and holds it against distortion, while at the same time it provides a convenient support for the sash pulleys.

Various changes in detail of construction and arrangement can be made to suit the conditions of use, and it will be understood that except as set forth in the accompanying claims the invention is not restricted to the particular construction and arrangement shown and described herein.
